megaTinyCore - burn bootloader error

[DanSkareda]

Hi. I have a clean instalation Arduino 1.8.15. I have installed only megaTinyCore (from *.json web address) and python3-3.7.2.post1-embed-win32v2a.zip (according to the instructions to python3). When I want to burn the bootloader for attiny1614, the burn ends with an error:

Traceback (most recent call last):
File "C:\Users\radek\AppData\Local\Arduino15\packages\megaTinyCore\hardware\megaavr\2.4.0/tools/prog.py", line 282, in
main()
File "C:\Users\radek\AppData\Local\Arduino15\packages\megaTinyCore\hardware\megaavr\2.4.0/tools/prog.py", line 112, in main
fuse_offset, fuse_val = fuse_str.split(":")
ValueError: not enough values to unpack (expected 2, got 1)

Do you know what's wrong? I also tried it in last version arduino beta 2.0 and there is the same error. I programming with pyUPDI SLOW. Sketches I upload without errors. The same error when burning the bootloader is also when I programming attiny3216.

We did it. But very difficult. I programmed the bootloader only with the megaTinyCore library version 2.4.2 in the folder in my sketchbook. But if I then want to load the program, I have to delete the library in the folder and I can only load the program via megaTinyCore version 2.4.0 (which is in the system via the *.json address). WTF??? It's all weird. Is it bugs in the library or what's going on?

Thanks for erports I was awae of tje bug shortly after the release of 2.4.0; This issue is resolved in 2.4.1 and later (2.4.1 was pulled because of other issues) . Please use 2.4.2 of megaTinyCore,and everyrthing should work.

Please use released version of 2.4.2 from board manager
